Modes of Operation
When these three conditions are met, the altitude preselect mode is
dropped and the system automatically transitions to the altitude hold
mode.
The altitude hold mode is dropped if the pitch wheel is moved. Altitude
preselect is automatically armed if the aircraft is 250 feet away from the
altitude preselect setting and has a vertical speed component in the
direction of the selected altitude.
The altitude preselect mode profile is shown in Figure 8--37 and
described in Table 8--7.
